MR-DF3 Portable High-Precision Dynamic Gas Distribution Meter
main feature
- Complies with the relevant standards involving gas distribution instruments in HJ57-2017, HJ604-2017, and HJ38-2017, supports multi-channel gas mixing and distribution, and can distribute various concentration standard gases such as ppb level, ppm level, and percentage level;
- It can be customized according to customer needs for dual-channel, three-channel, multi-channel and other composite gas distribution;
- Use high-quality components such as high-precision stainless steel mass flow controllers and high-precision rotameter to ensure high system gas distribution accuracy and reliable quality;
- Large LCD screen, the system runs more stably and the operation is easier;
- Flow control adopts closed-loop fuzzy control technology, with fast response and accurate flow control;
- Zero air pressure and cylinder air pressure can be monitored in real time to ensure that the air supply pressure meets the instrument requirements;
- The gas path cleaning function in the system can ensure the accuracy of each gas distribution and the long life of the equipment;
- No preheating time is required, gas distribution can be started when the machine is turned on;
- Can be used portablely, with built-in lithium battery, which can work continuously for 20 hours.
